you wont find "cheap"suzukis on TM anymore.. If you want too get something cheap for a project, get a Trade & Exchange or Loot or what ever the local buy and sell paper is too you...
Problem with the 410 (the reason I havent swooped at that price - well one of them) is to re-engine with 1300 or 1600 is a bitch. Not just a simple swap. The gearing isnt so easy to change as the newer versions (413 samurai). lighter weight axles, etc.
The 413 looks the part though as a tuff truck come play thing.
I would prefer to get a basic model and do all the cool panel bashing etc myself I guess.
I think I may lurk on TM for a while yet until the right bargain comes up or maybe I find one on TE, who knows - no time frame for me.
i´ve got a spare head which will bolt onto the 410 gives you 2 more horsepower than standard the heads used on the sc100 had some minor tuning done to them i just happens to have 4 engines a little more than i need
